Abstract

To assess the prevalence of equine coronavirus infection in riding horses, virus-neutralizing tests were performed on serum and saliva samples collected at four facilities in Japan. Seropositivity rates ranged from 79.2% to 94.6%, suggesting widespread circulation of the virus in these populations. Antibody prevalence in saliva samples from two facilities that had experienced outbreaks in the previous year (67.6% and 71.4%) was significantly higher than at the other facilities without reported outbreaks (41.7% and 45.2%, P<0.05). The presence of salivary antibodies in a high proportion of horses is therefore suggestive of recent exposure to the virus.
